Project X is a 2012 American comedy film directed by Nima Nourizadeh and written by Michael Bacall and Matt Drake based on a story by Bacall, and produced by director Todd Phillips. The film follows three friends—Thomas (Thomas Mann), Costa (Oliver Cooper) and J.B. (Jonathan Daniel Brown)—who plan to gain popularity by throwing a party, a plan which quickly escalates out of their control. The title Project X was initially a placeholder for a final title, but interest generated by the secretive title kept it in place. A nationwide open casting call was employed to find fresh faces. The majority of the cast were sourced from this casting call, but a few with prior acting credits, such as Mann, were accepted after multiple auditions. Filming took place on sets in Los Angeles over five weeks on a US$12 million budget. The film is presented as a found footage home video from the perspective of an attendee using a camera to document the night's events.
